Many argue that the 3.6 litre engine of this car is also better sounding. The 997.2 Carrera has only fractionally less horsepower than the 997.1 Carrera S, and has the advantage of a better cabin (namely the nav system, or PCM as it is referred to by Porsche) and is also meant to be immune to the IMS issue, better economy, improved breaks of the 997.1 Carrera, and updated exterior looks. Check out a company called LN Engineering for really detailed information about what is involved in swapping it out. Early cars with the smaller bearing can, in fact, have an advantage over later revised bearing 997.1's, as the fix to these LMS issues is far cheaper as less labor is required. The price of the early 997 reflects the potential issues, but if you find a car with a good service history and get your pre-purchase inspection done, you are in a good place. You should stay away from early 997, i.e., those delivered in late 2004 to some time in 2005 (do your own research to be 100% sure). But revised bearings are not a cure, so don't assume that a car equipped with this upgraded IMS bearing means there is no risk. The earlier cars fitted with the smaller IMS are more susceptible to major failure than those with the revised bearing. Dates on the various forums seem to alter, so don't always take everything they say to be gospel. These were changed, but you will need to do some research to be more precise. They scared me when I first read about them.Įarly 2005 cars had a smaller IMS bearing installed. I know that the tales on Porsche forums make for some pretty worrying reading in regard to these issues. I also want to point out that some models of 997 are less susceptible, if not immune, to all or any of these issues, either due to model type or year.
